Ok, I just turned 18 and lost my virginity to the girl I'm currently seeing (She has no clue I was a virgin.) Anyways, the thing is...I have a hard time ejaculating during intercourse. The thing is, I can go at it from every different position except one...and go at it for literally an hour without stopping yet I never climax.

On the otherhand, the only position this doesn't happen, is when she is on top. I can usually climax in about 8-10 minutes when she is on top.

I tried looking it up on google and the thing I'm finding is "Delayed Ejaculation" or "Retarded Ejaculation." But the thing is, I can climax regularly and just fine when I masterbate.
